 | GraphStageLogic.Grab<T> Method (Inlet) |
Once the callback
OnPush() for an input port has been invoked, the element that has been pushed
can be retrieved via this method. After
Grab< T> (Inlet) has been called the port is considered to be empty, and further
calls to
Grab< T> (Inlet) will fail until the port is pulled again and a new element is pushed as a response.
The method
IsAvailable(Inlet) can be used to query if the port has an element that can be grabbed or not.
